For me, when I start the evening by watching a well-crafted story, such as A Town Called Mercy, any episode after it had better match the quality or it's gonna be a letdown. The Power of Three was a letdown. They spent a long time doing exposition, then they rushed quickly through the ending. The medical science in this episode was poorly handled. The people who had died would remain dead. Getting a heart going is not the same as turning an on-off switch. We may be mechanical, but we are not that mechanical. And I still attempting to piece what happen in the seven weeks that Amy and Rory were with the Doctor. He takes to them to a 1890's hotel room where they will be pampered, then suddenly they running for their lives and Amy gets hitched with King Henry VIII. Huh? And what is it with the 1800s' that has sci-fi writers thinking this is a great century? It was a lousy century. Why not some future time and place? Certainly, there are places that are more pleasurable and relaxing than a stuffy 1890s' hotel, even if it is posh by 1800's standards like the Savoy. And, can someone please tell me why Amy and Rory needed the blessing of Dad Rory for them to go an adventure? It wasn't important before, and, since one hopes that they are adults, they can make choices for themselves. I felt the father was handled poorly. Though I understood how Rory can be patient for 2000 years, I feel that the father was a source of comic relief. I didn't like it at all. There was only one moment that I felt worked, and that was when the Doctor was having a frank discussion with the father about past companions. For the life of me, I can't remember which companions got left behind. Overall, I think this is one of the weakest episodes for the eleventh doctor. I am hoping that next week can be better. It can't be worse.

Of course I can understand it if you didn't like the show. The rushed ending for example is an obvious flaw of the episode, and I guess it may ruin the whole thing for some people. But non-convincing depiction of medical science and poor taste in centuries? Now that's a very unusual selection of grievances.
